Specification of Letters Patent.

Application filed September a, 1916. Serial no. 119,065.

To all whom it may concern: Be it known that 1, JAMES A. GRAY, a citizenof the United States, residing at the city and county ofSan Franciscoand State of California, have invented certain newtmd usefulImprovements in Apparatus for.

Forming and Flanging Can-Bodies, of which the following is a specfication.

Thepresent invention relates to can makof food. products orothermaterial, are frequently flattened by compressing opposite sides,in order that they may occupy less space during shipment and storage. Itis necessary, therefore,-to restore these flattened can bodies to theiroriginal shape before applying the first end or bottom thereto. Theobject, of the present invention is to provide a machine which may beused by a packer who has receivedand stored his sup:

, ply of cans in flattened form, for reforming the machine, certain saidcans and forming the necessary flanges on the ends thereof for havingappliedther'eto flanged ends.

In order to comprehend the invention,

reference should be-had to the accompanying sheets of drawings, where n:

Figure 1 is aside elevation of the com-. plete machine.

Fig. 2 is a sectional plan view looking in the direction of Fig. 1.

Fig. 3 is a of the arrows on,tl1e line 2.2

part sectional end elevation of parts being omitted for the sake ofclearness.

Fig. 4 is a vertical section tlirough "thefeed mechanism, taken onrlineie-4 of Fig. 2

and viewed in thedirection of the arrows;

Fig. 5 is a longitudinal sectional detail taken on the line 5-45 of Fig.3 and viewed in the direction of the arrows, showing the flangingmechanism.

. In the drawings the reference numeral 1 designates any suitablyconstructed base or bed-plate, which is preferablysupported upon legs 2,as illustrated in Fig. 1 of the drawings particularly. 1 v

Mounted upon the bed-plate 1 is' a superstructure 3, in which isjournaleda horizontal transverse drive shaft 4, Figs. 1 and 2 of thedrawings. This shaft 4 constitutes the main driving means for the entiremachine, and is shown'as carrying a belt-pulley '0 at one end, by meansof which said shaft may be driven.

A mutilated worm 6, Fig. 2 of the drawings, fixed upon the drive shaft4:, and meshing with a Worm-wheel I mounted upon ashaft 8,-disposed atright anglesto the driveshaft 4, imparts an intermittent rofary movementto said shaft 8. The shaft 8 is gournaled in a superstructure 9,Wlll(3l1is supported by the previously mentioned superstructure 3.

tion, is secured upon oneend of the shaft 8,

shown in the drawings as comprising a screw y 13 secured to the free endof each stud 11.'

Another horizontal-shaft MfFigs. '1, 2 and 3 of the drawings, parallelto theshaft 8, and below and to one side thereof, is journaled inbrackets 17 and 18 mounted upon the bed plate 1, and is continuouslydriven by the, drive-shaft 4 through suitable bevel gears 15 and 16.Ayoke 19, Figs. 1 and 3 of the drawings, is pivoted atone end concentricwith the shaft ldand in its outer end carries ashortrotatablymountedshaft 21, said shaft: 21' being driven by the shaft 14 through suitablespur gears22 and 23, and carrying an ironing or reforming roller 20,

positioned parallelto and adapted for contact With the cylindricalportions of the mandrels 12, when said mandrels are successively broughtinto. position by the intermittent ro tation of the turret 10. Contactbetween the roller 20 and the positioned mandrel 12 is preferablysecured by means of a plate 24, Figs. 3 and 5 of the drawings, slidablymounted. upon studs 25 hired to the under sideof the bedlate 2, saidplate 24 being ressed upward y by springs 26, and

the bed-plate 1 by means of two. spaced vertically disposed bracketmembers 28, Figs. 1,

2 and- 3 of" the drawings, WhlOh support, by

means of angle brackets 29, Fig. 1, an inner pair of spaced verticalplates 30, Figs, 1, 2

and 4, having angle members 31'fixed to their edges, said plates 30 andangle mem- .;bers 31 forming a vertical magazine for the reception of astack of flattened can bodies 32. Immediately beneath the magazine thusformed is a horizontal guide plate 34, Figs.

1, 2, 3 and 4 of the drawings, in the guide ways 36 of which iscarried asliding member 35. Horlzontal reciprocating motion 1 may be imparted tothe slide 35 by any is fixed two forwardly extending convenient meansthe same comprising, in the present instance, 2. lug 37, Figs. 1 and 4of the drawings, on the under side of said slide 35, a lever 38connected to said lug 37 by means of a link 39, said lever 38 beingfulcrumed at 40 to a bracket 40 extending fromone of the legs 2 of themachine, and

being connected by a pitman rod 41 to an eccentric strap'42 WhIChsurrounds an ec'- centric 43 fixed upon the drive shaft 4.

The slide35 carries an upwardly extending lug44, Fig. 4 of the drawings,to which fingers 45 adapted to engage the lowermost can body 33 of thestack of can bodies 32 contamed within the magazine 30* and to push saidlowermost can body out of said magaz ne and on to spaced guide members46 ad acent thereto, each of said guide members 46 being carried by apair of swinging spreader arms 47.- Said swinging spreader arms47,,Figs. 1, 2 and 3 of thedrawings are mounted in pairs upon each sideof the magazine supporting brackets 28, and have inwardly projectinglower ends 48 formedwith notches 49, adapted to engage the can body 33when dropped, as hereinafter described, from its position upon the gu demembers 46, and by laterally compressing said can body, to spread orexpand it preliminarily. Said pairs of arms 47 are mounted upon and 51,the shaft 51 being extended, as

shown in Fig. 1 of the drawings, through a journal bracket 52, andcarrying on its end a lever-arm 53, Figs. 1 and 3 of the drawings, saidlever-arm being connected by a vertically disposed. pitman rod-54 with ayoke 55 embracing the drive-shaft 4, and carryin a cam-following roller56, adapted to lie within and follow the groove 57 of a cam member 58,secured upon the driveshaft. Oscillatory motion is thus imparted to theshaft 51, and is transmitted. to the shaft 50by means of a bar 59,connecting levers 60 and 61, extending in opposite dispaced horizontalshafts 5O tively. Thus the opposite pairs of swinging arms 47 are causedto swing in and out simultaneously and in opposite directions.

The outward movement of the swinging spreader-arms 47 causes aseparation of the guide members46, thereby permitting the can-body 33 todrop into the notches 49 of said spreader arms. The subsequent inwardmovement of said arms compresses said can body laterally and therebyspreads the same by an amount sufiicient to permit the entrancethereinto of a pair of spaced spreader rods 62, Figs. 1, 2 and 4 of thedrawings and a spreader liorn 63 positioned between said spreader rods62, said rods and said horn being carried by, and projecting forwardlyfrom, the lug 44 of the slide. member 35. .Saidslide also carries a pairof spaced forwardly extending fingers 64, positioned below and extendingbeyond the spreader horn 63, as shown in Figs. 3

and 4 of the drawings, for engaging the end of a partially opened canbody 33 and forcing the same onto a mandrel 12 positioned in properalinement therewith. n apertured guide-plate 65, against whichthepreliminary spread can body 33 abuts, retains said can body in positionduring the entrance there'into ,of the spreader rods 62 and the spreaderhorn 63.

Thus it will be seen,'by reference to Figs.

2, 3 and 4 of the drawings, that in the present case three completestrokes of the slide member 35 are required to transfer a flattened canbody from the magazine 30 to a positioned mandrel 12. The first inwardstroke of said slide removes the lowermost can body 33 from the magazineby means of the pusher fingers 45, and pushes the same upon the guidemembers 46 carried by the swinging arms 47, Figs. 1 .and 4 of thedrawings. During the return movement of the slide 35 said swinging armsare separated and brought together as previouslv described, to permitsaid can body 33 to drop into the notches 49 and to be laterallycompressed thereby, and preliminarily opened. 'The second inward strokeof the slide '35 causes the introduction into the preliminarily openedcan body 33 of the spreader rods 62 and the spreader horn 63, therebyfurther. expanding and spreading said can body. At the same time thesuctherein a Hanging been preliminarily opened by the swinging arms4e7,is further opened by the spreader. rods and spreader horn, and the thirdflattened can body is removed from the maga- Zine by the pusher fingers4:5, and positioned upon the guide members 46.

The can-body 33', positioned upon'the mandrel 12 at the position A, Fig.3 ofthe drawings, is then carried by the intermittent rotation of theturret 10 to the posi-. tion B, at which position it is not acted upon.The next movement of the said turret carries said can body .33 to theposition C, whereit is ironed and restored to its cylindrical form bycontact with the revolving ironing roller 20. The following movement ofthe turret 10 carries the reformed can body-to the position D, at whichthe 'flanging operation takes place. 7

This Hanging is accomplished by the following mechanism: The mandrel 12is formed near its inner end, as shown in Figs.

2 and 5 of the drawings, with a portion 66 a of enlarged diameter, thediameter thereof bein that of the interior of the reformed can body. Ashoulder 67, having formed oove 68, is formed upon the mandrel12Qad]acent 'to and behind 1 said enlarged portion 66.. A reciprocatinging die 69, adapted to be introduced over the end of the mandrel 12, hasat its free end an annular portion 7 0 of a diameter sufficient toenable it to enter the end of" the reformed can body 33. i A shoulder71, having formed therein a fianginggroove 72, is formed upon said die69 immediately back of the portion 70. Thus by forcing the die 69'overthe end of the mandrel 12 and against the end ofthe can body 33" carriedthereby, the ends of .dll

said can body are forced over the'enlarged portions 66 and 70 of themandrel 12 and the die 69 respectively, and said ends of said can body33' are flanged outwardly by the flanging grooves'68 and 72.,Reciprocating motion is imparted to the die 69 by means of a sliding rod73, by which said die is carried, said rod being suitably supported in abracket 74, and having its outer end connected at 75, Figs. 1 and 2 ofthe drawings, with a lever 7 6, said lever being fulcrumed at 77, andcarrying a roller 78 adapted to follow a groove cam 79 carried by theend of the rotating shaft 14:. It is to be under stood that the movementof the flanging die 69 is so timed with relation to the movement of theturret 10, that each can body is flanged at the position D, Fig. 3 ofthe drawings.

1 At the position Ethe reformed and flanged can body is ejected from themandrel 12, into any suitable place of deposit not shown in thedrawings, by an ejector finger 80, Figs. 1, 2 and 3 of the drawings,carried upon the end of a slidably mounted rod 81.

said rod passing through the hollow turret-Q.-

ang-

of the swinging-arms 47 and" is compressed 1ink82, Figs. 1 and 2, alever 83, fulcrumed at 84, and having its lower end connected at 85,with rod 86, extending under the ma-' chine to the lever.38, andpivotally connectedtherewith at 87.

To enable the ejector finger 80 to pass behind the inner fianged end ofthe can body to engage the same for the purpose of eject ing it from themandrel, said canbody must be initially moved upon said mandrel, to freethe inner flanged end from the flanging groove 68. F or this purpose astationary cam member 88, Figs. 1, 3, and 5 of the drawlngs, isprovided, said cam member bebody is suflicient to free the inner end ofsaid can body from the enlarged portion 66 of the'mandrel 12, so thatsaid can body is loose upon saidmandrel, and can be easily engaged andremoved by the ejector finger 86.

The operation of the .machine. may be briefly summarized as followst Asupply of 9.5

flattened can bodies 32 is placedin the magazine 30 ,-.the lowermost canbody 33 resting upon the pusher fingers 45'. Upon the withdrawal andsubsequent return movement of the slide 35, said lowermost flattened canbody 33 is removed from the bottom of the magazine 30 by said pusherfingers, and POSltlOIlBd upon the guide members 46. Said can body isthen engaged by the notches 49 laterally thereby. The spreader rods 62and the spreader horn 63Iare then introduced into saidv can body tofurther spread or open the same, after which, upon the nei'rt inwardmovementof the slide 35, the can I body is forced onto the positionedmandrel 12. Theintermit'tent rotation of the turret -10 carries themandrel 12, with the partially reformed can body 33' thereon, to theposition C of Fig. 3 of the drawings. ln this position the ironingroller 20, revolving in contact with the can body 33, restores the sameto its original cylindrical form. The reformed can body is then. carriedto the position D,..where endfianges are formed thereon by action 'ofthe Hanging die 6911s hereinbefore described. v

The next movement of the turret 10 carries the reformed and flangedcanbody to the position E, where said can body is 're movgg from themandrel by the ejector linger V The various interworking parts of .themachine are so timed-asto act successively upon can bodiespositioned-upon each of the Alto mandrels 12, carriedby the turret 10.Thus as each of said mandrels 12 passes the position A, Fig. 3 of thedrawings, a flattened can body is partially spread and pushed thereupon,and each can bodyis reformed at the'position C, flanged at the positionD,

and ejected at the position E, as its mandrel is successively carried tosaid positions.

The invention has hereinbefore been described and' is herewithillustrated in its preferred form. It is to be understood however, thatvariations may be made in the construction and arrangement of theworking parts of the machine without altering,
